Video Analysis and Muscle Physiology
Our biology staff scientist, John Melville, has been working with our new LabQuest Mini and has found a way to integrate video analysis into a simple muscle physiology experiment. EKG sensors are attached to the bicep and forearm muscles to record muscle activity. A Low-g Accelerometer is then attached to the wrist to measure joint angle. The video capture feature in Logger Pro is then used to synchronize video from a DV camera and the physiological data from the LabQuest Mini. The subject is filmed performing a simple bicep curl. Students can then clearly see that muscle activity precedes movement of the arm and that the forearm muscle activity precedes activation of the bicep.
LabQuest Earns Five-Star Review
The Vernier LabQuest just received a wonderful review in MultiMedia & Internet@Schools, an educational publication. The review gave the LabQuest a 5-Star rating (out of 5) with the following grades:
- Installation: A
- Content/Features: A
- East of Use: A
- Product Support: A+
“Students will enjoy using LabQuest…. I was impressed by the rugged construction. This is definitely a tool that will last, which makes it an excellent buy—especially with today’s tight funding…. I have no doubt that LabQuest is going to get plenty of use in my classroom. I would highly recommend it for every classroom that is serious about engaging students in meaningful scientific investigations.”

Redesigned O2 Gas Sensor
The O2 Gas Sensor measures oxygen concentration in air, and with its wide measurement range, the O2 Gas Sensor can also be used to monitor oxygen concentration during human respiration.
Redesigned CO2 Gas Sensor
Perfect for everything from the respiration of peas to the respiration of humans. Our new CO2 Gas Sensor now has two ranges: 0-10,000 ppm for plant respiration and photosynthesis, and a high range of 0-100,000 ppm for human respiration.
Vernier LabQuest
Vernier announces breakthrough data-collection technology for science education—the Vernier LabQuest.
LabQuest works as a stand-alone device or as a computer interface, providing the versatility to excel in the classroom or in the field.
The Vernier LabQuest includes built-in software for data collection, graphing, and analysis, and on-board applications such as a periodic table and stopwatch. Use the powerful and intuitive software from the vivid color touch-screen—all packed in a rugged and water-resistant exterior.
The freedom to inquire. The technology to excel. The Vernier LabQuest.
Human Physiology with Vernier
Our new and highly anticipated lab book, Human Physiology with Vernier, contains 24 human physiology experiments designed to encourage students to think about the physiology of various human organ systems. These activities involve using Vernier sensors such as the Spirometer and Hand Dynamometer to measure the activity of the upper respiratory tract, the lungs, the heart, the nervous system, and the musculoskeletal system.
Spirometer
Our new Spirometer is ideal for monitoring inspiratory and expiratory air flow and for making lung volume measurements.
Hand-Grip Heart Rate Monitor
Use the Hand-Grip Heart Rate Monitor to measure heart rate at rest and during activity.
Blood Pressure Sensor
This non-invasive sensor uses a cuff and a differential pressure transducer to measure human blood pressure.
Hand Dynamometer
Use this strain-gage isometric dynamometer to measure grip strength and perform studies related to muscle fatigue.
